Surface roughening of metallic substrates by high pressure pure waterjet

The dependence of critical process parameters was found for the use of a high pressure jet of pure water to controllably erode superalloy substrates with a minimal thickness loss. Adequate roughness was obtained for subsequent thermal spray coating of an MCrAlY overlay.
